BICYCLE.

SPECIFICATION forming part of Letters Patent No. 480,166, dated August2, 1892.

Application filed March 7, 1892- Serial Nn.424,033. (N0 model.)

To all whom it may concern.-

Be it known that I, ARTHUR JOHN BAT- TERSBY, (of the firm of A. J.Battersby & Sons, feather purifiers,) a subject of the Queen of GreatBritain, and a resident of Nottingham, England,have invented certain newand useful Improvements in Bicycles, of which the following is aspecification, reference being had to the accompanying drawings.

In the drawings, Figure 1 shows a left side view of my improvements asapplied to a Safety bicycle; Fig. 2, a plan of the same. Fig. 3 showsthe left side view of a coverplate, referred to hereinafter. Fig. 4shows a vertical sectional view of the bracket A, taken on the line a a,Fig. 2.

I employ a two-armed bracket A, secured totheframingBBof each bicycle.The bracket forms bearings for the pedal-axle A, which is somewhatlonger than usual and provided-on one side of the bicycle with aninteriorlytoothed wheel A The arms projecting frem the back of thebracket carry bearings for a second axle 0, having two cranks 0,provided at one end with a toothed spur-wheel A gearing into the teethof the Wl166lA The arms of the bracket are secured to the front ends ofthe usual framing B B of the bicycle. The back ends form bearings forthe axle D of the back driving-wheel D Between the bearings and thedriving-wheel the axle D forms two cranks D, each revolving in a bearingat the back of a connecting-rod D The front ends of the rods formbearings in which the cranks G of the second axle revolve. Theback-stays B of the bicycle have their lower ends bolted to the bearingsat the back ends of the framing B in the usual Way.

To prevent access of dust to the teeth of the wheels A A I employ acover-plate A A portion of the plate is broken away at Fig. l to showthe wheels gearing into each other.

The plate is provided with two holes, (shown at Fig. 3,) in which theaxles A and C revolve and keep it in position.

The pedal-axle is provided with the usual pedal-arms a a (Only partlyshown at Figs. 1 and 2.) Each revolution of the pedal-axle carrying theWheel A causes the wheel A and the two cranked axles O and D anddrivingwheel D to revolve thrice.

By the addition of the above-described parts to a Safety bicycle I amenabled to dispense with the driving-chain and its adj ustmentsheretofore employed and attain a greater speed at each revolution of thepedalaxle.

WVhat I claim is- 1. The combination of a two-armed bracket A with theframing B B and B B of a bicycle, the back ends of the framing BBforming bearings for the axle D of the drivingwheel D of a bicycle.

2. In a bicycle, the combination of a twoarmed bracket A, formingbearings for a pedal-axle A, with an axle 0, provided with two cranks O,and the pedal-axle carrying a toothed wheel A gearing into a wheel A onthe axle 0, both wheels being covered by a plate A", substantially asdescribed.

3. In a bicycle, the combination, with a pedal-axle, of a two-armedbracket in which said axle is journaled, a second axle O, journaled inthe arms of said bracket, a toothed wheel A carried by the pedal-axle, atoothed wheel A carried by the second axle and gearing with the wheel Athe cranks O G, and connections between the same and the driving-wheel,substantially as described.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.

ARTHUR JOHN BATTERSBY.
